DeviceLock (ALPHA platform) - Version 3.1 DeviceLock allows network administrators to specify which users can access which devices (ports, floppies, MOs, and so on) on the local computer. Once DeviceLock is installed, administrators can assign permissions to LPT ports, CD-ROMs, COM Ports, or any other device, just as they would to any share on the hard disk. Network administrators may use DeviceLock to flush a storage device's buffers (very useful for removable media) and to get extended information about devices and NTFS partitions. Version for INTEL x86 platform is also available.
